========================================================
Explanation:
Consider an example like 3, 6, 12, 24, 48, ...
The ratio between consecutive terms is
6/3 = 212/6 = 224/12 = 248/2 = 2Each time we divide any given term over its previous one, we get the same ratio 2. We call this the common ratio. In terms of notation, the variable r is used for the common ratio, so r = 2 in this case.
As another example, the geometric sequence 5, 50, 500, 5000, ... has r = 10 as the common ratio because we multiply each term by 10 to get the next one. Moving forward has us multiply by r, moving backward and we divide by r. The value of r cannot be zero, but it can be negative.
An example with r being negative would be something like
1, -1, 1, -1, 1, -1, ....
we just bounce back and forth between those two values. In this case, r = -1.

Find the length of the arc.
Answer:
[tex]\frac{5\pi }{2}\:ft[/tex] (Option D)
Step-by-step explanation:
GIVEN :-
Angle subtended by the arc at center (θ) = 90°Radius of the circle = 5 ft.TO FIND :-
Length of the arcGENERAL FORMULAE TO BE USED IN THIS QUESTION :-
Lets say an arc subtends ∠θ at the center of the circle whose radius is 'r'.
[tex]=> Length \; of \; the \; arc = \theta \times \frac{\pi r}{180}[/tex]
SOLUTION :-
Length of the arc = [tex]\theta \times \frac{\pi r}{180} = 90 \times \frac{5\pi }{180} =\frac{5\pi }{2}[/tex]
I WILL GIVE BRAINLIEST PLEASE
Answer:
the answers are pi/6 and radius. hence the statement should read as
the length of the arc intercepted by third central angle is pi/6 times the length of the radius.
It takes 3 hours for a boat to travel upstream against the current and 1.8 hours to travel the same distance downstream with the current. What is the speed of the boat in still water if the speed of the current is 3 mph?
Answer:
Step-by-step explanation:
There are a couple of things to know before we set up the table for this problem. First, we need to remember that if the boat is traveling against the current, that the current is going to slow the boat down; likewise, going with the current will speed the boat up. Second, we need to realize that if the boat's distance against the current is the same as the distance with the current, then the distances in the equations will be set equal to one another.
Set up the table with U (against the current) and D (with the current) on the outside and fill in what we are given:
d = r x t
U
D
This is the table. Now we will fill it in:
d = r x t
U r - 3 x 3
D r + 3 x 1.8
The formula for the distance equation is at the top of the table as d = rt. We already decided that the distances that the boat traveled upstream and downstream were the same so we will set those d values equal to each other, but we first need to get the d value for each row. If distance = rate times time, then for the first row:
d = (r - 3)3 and
d = 3r - 9. For the second row:
d = (r + 3)1.8 and
d = 1.8r + 5.4. Setting them equal to each other:
3r - 9 = 1.8r + 5.4 and
1.2r = 14.4 so
r = 12 mph

What is the measure of angle 2 in degrees?
Answer:
The measure of angle 2 is... 60 degrees.
Angle 1 - 93 degrees
Angle 2 - 60 degrees
Angle 3 - 27 degrees
Find the missing angle measure, arc measure of solve for x. Show all work!
Answer:
hmmmmm
Step-by-step explanation:
Answer:
m∠SRT = 47°
Step-by-step explanation:
The measure of an inscribed angle is 1/2 the measure of the intercepted arc.
So,
16x - 1 = 1/2(30x + 4) = 15x + 2
x - 1 = 2
x = 3
m∠SRT = 16(3) - 1 = 48 - 1 = 47

find the equation of the parabola with its focus at (5,0) and it’s directrix y=2
Answer:
Option A
Step-by-step explanation:
From the question given in the picture attached,
Directrix of the parabola → y = 2
Focus of the parabola → (-5, 0)
Since, focus is below the directrix, parabola will open open downwards.
Equation of the parabola will be in the form of,
y - k = -4p(x - h)²
Here, (h, k) is the vertex of the parabola
p = Distance between vertex and focus or distance between vertex and directrix
Since, distance between vertex and focus = Distance between vertex and directrix
Therefore, vertex of the parabola → (-5, 1)
Now distance (p) between vertex (-5, 0) and focus (-5, 1) = 1 unit
By substituting these values in the equation,
y - 1 = -4(1)[x - (-5)]²
y - 1 = -4(x + 5)²
y = -4(x + 5)² + 1
Option A will be the answer.

Find the slope of the graph below. Help fast
Answer:
2x
Step-by-step explanation:
(5,5) is a point (I reckon it is from the screenshot you sent at least)
(0,-5) is a point
-5 - 5 = -10
0 - 5 = -5
-10/-5
Slope = 2x
Answer:
Two Possible Points:
5,5 and 6,7
7 - 5 2
____ = _____ = your slope is 2
6 - 5 1
When picking two points subtract the y(rise) from eachother first which will be your numerator and the x(run) from eachother in the same exact way you subtracted to the y which will be your denominator.

Jensen goes to the store with $4. He buys 3 pencils for $0.70 each and
some erasers. Each eraser costs $0.50. Enter the maximum number of
erasers he can buy.
Answer:
3 erasers.
Step-by-step explanation:
Let p = pencils and e = erasers. Since we know that Jensen has $4, we can set up the following inequality and solve for e.
0.70p + 0.50e ≤ 4
0.70(3) + 0.50e ≤ 4
2.10 + 0.50e ≤ 4
0.50e ≤ 1.90
e ≤ 3.8
Since erasers are usually bought as whole items, the maximum amount of erasers Jensen can buy is 3.
A DrillingRick was diggingA well in the valley it dug to a point of -50 Meters in one day After 18 hours at how many meters would the rig be if it moved at the same amount each hour? Show your work.Explain your answer
Answer:
37.5 meters
Step-by-step explanation:
depth of well : hours of digging
it dug to a point of -50 Meters in one day
= 50 meters : 24 hours
After 18 hours at how many meters would the rig
Let
x = depth that will be rigged
depth of well : hours of digging
= x meters : 18 hours
Equate the ratios
50 meters : 24 hours = x meters : 18 hours
50/24 = x/18
50 * 18 = 24 * x
900 = 24x
x = 900/24
x = 37.5
x = depth that will be rigged = 37.5 meters
